Description

In the Linux kernel, the following vulnerability has been resolved:

IB/rdmavt: add lock to call to rvt_error_qp to prevent a race condition

The documentation of the function rvt_error_qp says both r_lock and s_lock
need to be held when calling that function. It also asserts using lockdep
that both of those locks are held. However, the commit I referenced in
Fixes accidentally makes the call to rvt_error_qp in rvt_ruc_loopback no
longer covered by r_lock. This results in the lockdep assertion failing
and also possibly in a race condition.
